Kelsea Ballerini joined an unusual Nashville lineup when she performed on stage with Cyndi Lauper and Ingrid Michaelson during a rousing rendition of Lauper’s 1983 hit song “Girls Just Wanna Have Fun.”

Opening the Skyville Live web series with “Peter Pan,” Kelsea Ballerini loved working with both Lauper and Michaelson.

The three posed for selfies that were shared on social media.

“Girls just wanna have fun,” Ingrid Michaelson captioned this shot of herself alongside Kelsea Ballerini and Cyndi Lauper.

In this next post, dubbed “Girls just wanna have fun part deux,” Kelsea Ballerini puckers up for the picture.

Cyndi Lauper shared a photo, too, and captioned it, “Ok. One more for now. ?? #ingridmichaelson #kelseaballerini.”

While it may be hard to fathom these three coming together to make amazing music, it shouldn’t. Cyndi Lauper is actually joining the likes of Kelsea Ballerini in making a country album. “Detours” is set to drop in May.

Kelsea Ballerini, by the way, just learned she’s been nominated for “Female Vocalist of the Year” at the upcoming ACM Awards.
